Automotive gear parts Applications and Precision Gear Manufacturing
UNITECH-GEAR specializes in plastic gear mold development and precision gear injection molding for automotive applications. Power window transmission gearboxes are now a standard configuration in virtually all vehicles on the road today.
The core component of automotive window systems is the window regulator (window lift mechanism). Each window has a small DC micro motor on the side, controlled by switches on the door panel or central console to start and stop the motor. Each motor shaft connects to a reduction worm gear, and through gear-worm meshing, achieves angle conversion and forward/reverse motion at constant speed.
The gear connects to the glass linkage to achieve up/down glass movement, or alternatively connects via steel cables for reciprocating motion. UNITECH-GEAR automotive power window worm gears and connecting gears feature compact structure, precise transmission, and weather-resistant wear characteristics. Materials typically include PA6+15%GF, PA66+30%GF, and other engineering plastics.
UNITECH-GEAR Gears — High Precision, Low Noise, Long-Lasting Durability
Mastering Core Manufacturing Technology — Pursuing Excellence
Design-Driven, Analysis-FocusedExperienced Engineers Optimize Tooth Profile Design
- Gear design analysis software optimizes tooth profiles, improving safety factors and service life.
- Close communication with customers to understand product functional requirements including material selection, mechanical strength, dimensional accuracy, surface finish, and service life.
- Rigorous design review process: pre-design structural discussion, designer self-inspection against checklists, and post-design review with manufacturing teams.
Processing-Driven, Precision-FocusedFrom Mold Design to Injection Molding — Precision Manufacturing
- Independent machining department for copper electrode (EDM electrode) design and manufacturing. Post-machining copper electrode surface roughness reaches Ra 0.3, accuracy up to JIS Grade 0 (highest level).
- Mold cavity mirror finishing using Charmilles C-axis EDM, achieving surface roughness of Ra 0.3 and accuracy within 0.001mm.
- Japanese brand high-precision injection molding machines produce gears with dimensional tolerances within 0.03mm and weight deviation typically below 0.7%.
Detail-Driven, Control-Focused100% Visual Inspection — Full Testing Before Shipment
- Advanced inspection equipment: gear meshing testers, CMM (Coordinate Measuring Machines), roundness testers, and electron microscopes ensure product quality.
- Strict implementation of ISO 9001 quality management system ensures all products meet customer requirements.
- All gear products undergo 100% visual inspection before assembly, and all gearboxes are fully tested before shipment.
